注意：经过测试，不能够直接处理字典或者数组

otherObject.testChar     = 'c';

playground.otherObject   = otherObject;
NSString *jsonString     = [AJSerializer jsonStringWithObject:playground];

NSLog(@"json string is %@", jsonString);
}

打印的信息：

2015-01-04 20:52:18.399 AnyJson[3825:149779] json string is {"testInteger":0,"otherObject":{"isTest":true,"name":"casa","testInteger":13,"testChar":"c"}}
